6 Claims.

.This invention relates to a package for the interliner used by opticians in the shimming of frames for eye glasses; and the invention has for one of its objects to place this interliner material in a more convenient form for handling and maintaining the same in a cleaner condition.

Another object of the invention is to provide a package from which the material may be easily and quickly drawn and clipped oif at the desired length, leaving the remainder of the package in its original packaged form.

Another object of the invention is to maintain a portion of the interlinerprojecting from the package in order that it may be readily grasped for pulling the desired amount from the package.

Another object of the invention is a simplified method of assembling the package. 1

With these and other objects in View, the invention consists of certain novel features of construction, as will be more fully described. and particularly pointed out in the appended claims.

In the accompanying drawings:

Fig. 10 is an edge view of the modified form of package shown in Fig. 9.

Interliner material of Celluloid or like material in strip form, usually arcuate in cross section, and used for shimming eye glass frames, is usually furnished in loose rolls or in metal boxes. The material in such form is dcult to handle and store. Some care must be taken that the coils do not become disrupted to such an extent as to become snarled or tangled with other working equipment, and the handling of coils of even short lengths is clumsy and difficult. In order to provide for more convenient handling of the same, I have provided a package in which the material is provided in a spiral coil, held in a casing of a pair of transparent discs whose edges are so formed as to come together and provide acomplete package enclosing the coil, or optionally notched to maintain the material protruding therefrom, and yet the discs are suiciently resilient so that the material may be obtained by spreading the discs sufciently to grasp the edges of the material and then pull the material by the spreading of the discs progressively around their periphery; and the following is a more dei tailed description of the present embodiment of this invention, illustrating the preferred means by which these advantageous results may be accomplished.

With reference to the drawings, the sheet stock parts of my package consist of a core I0, Celluloid discs I2 each beveled or flaring inwardly as at I8 and a pair of Celluloid washers I6. Each of these parts is provided with an opening and is assembled upon an arbor 25 (see Fig. 6) of a size to just iit this opening and bring the openings and the various parts into registry. This pin is urged upwardly by a spring 26 located in bore 21 in a block 28 carrying a cap 29 thereon and is shouldered as at 30 to limit the upward extension of the pin.

A pin I4 is used to hold the package in assembled relation and is square in cross section and sharpened at its end as at 32. This pinv is forced downwardly by a plunger 3|, as shown in Fig. 6. The plunger forces the arbor 25 inwardly by reason of the resilience of the spring 26 and causes the pin I4 to force its way through the washers, discs and core to become rigidly fixed in all of these parts by reason of its square cross section, as illustrated in Fig. '1. r

Two projecting portions of the pin, as shown in Fig. 8, may be grasped in a chuck 34 and turned so as to assemble the interliner material 2| which is 'started by inserting one end in slot 23 in the core, as illustrated in Fig. 5, and then by turning, the interliner material is spirally wound as at I I into the package and is of a width to be guided by its opposite edges contacting the discs I2.

After winding the interliner into position, the ends of the pin I4 are cut off and caps II are positioned over the ends of the pin, as illustrated in Figs. 2, 3, 4, or 10.

In some instances, the interliner may be completely enclosed within the disc I2, as illustrated f to make more accessible this material and also in Figs. 1, 2, and 3,

while in other cases, the disc may be notched as at 36 so as to maintain an end of the interliner in exposed position for ready grasping by the hand.

From the manner of assembly, it Will be readily apparent that the pin locks all of the parts together against relative rotation. It is desirable that there be a rotation of the large discs I2 relative to the remaining parts for ease in unreeling as these are the parts usually grasped in one hand, and accordingly as these parts are thin, I may cause them to be rotatable relative to the rest of the assembly by merely twisting them upon the pin to enlarge the hole and make the same round instead of square, that rotation of these discs may be had.

The washers may be of a color distinguishing from the color of the core, while the caps may be of still a different color or of a color matching the color of the core so as to provide a handsome contrast and a decorative package.

The discs I2 are transparent so that the interliner material maybe viewed through the discs. The thin, transparent discs I2, however, are sufliciently iiexible so as to easily move into dotted line position as shown at 20 in Fig. 3 or as. shown in Fig. 4. When the end 2| of the material is grasped and pulled, the .discs will revolve, as will also the material, about the core, and the discs will be progressively spread apart about their periphery as shown in Fig. 4, permitting the desired amount of material to be drawn from position.

It Vwill be apparent that this device may be made in various sizes to receive different coil lengths of interliner material.

I claim:

1. A package of interliner material comprising a core, a spiral coil of a length of material about said core, a casing comprising discs extending over either side of said coil to confine and align the coil between them, and a pin extending centrally through said core, said core being fixed on said pin and said discs being rotatable with reference thereto, and means extending radially from said pin and engaging the outer surface of said discs to secure the same in said relation.
